CENTBH'UGAL FAN AND TURBINE-ENGINE.

To all whom it may concern:

Be it known that I, Lnvr JULIAN WING, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Centrifugal Fans and Turbine-Enginea 'of which the following is aspecification.

The present invention relates generally to fans and has more particularly reference to a combined fan and turbine motor. 1

The chief object of the invention is to produce a structure combining a fan or air current producer and a turbine motor of such a character that the exhaust steam from the turbine will pass a direction parallel to the axis of rotation of the fan and will mingle with the air current produced by the fan, so that the combined air and steam may be utilized for the purpose of a forced draft device for boilers &c. v I

To this end the invention comprises the features of construction, combination of parts and arrangement oi elements hereinafter set forth.

In the drawings the invention is embodied in a concrete and preferred form; but changes of construction may of course be made without departing from the legitimate and intended scopeoi the invention.

In the said drawings: Figural is an end elevation of a I combined fan and turbine motor embodying the invention. Fig. 2 is a sectionalview on the lines :e-m-o: of Fig. 1. Fig. 3 is a diagrammatic view of one of the vanes and the adjacent nozzle for causing steam to im-' pinge thereon. Fig. 4 is a vertical sectional view of a slightly different construction from that shown in Fig. 1. Fig. 5 is a detail view in elevation of a portion of Fig. 4. Fig. 6 is a plan view of Fig. 4 with parts broken away. 7

Similar characters of reference indicate correspondparts in the several views. A indicates a casing of a suitable construction having the cm! arms 1 and 2 extending diametrically across the casing. These emu arms are provided with the lugs K and K supporting the shaft 1.

ing buckets D at their periphery. In Figs. 1 to 3 the outer ends of the vanes form buckets the plane of whose impact surfaces is substantially parallel to the axis of rotation of the vanes as shown, while in 41:0 6 the buckets are shown as separate members.

At a convenient point is placed a supply pipe E for the steam provided with laterally extending pipes F and F terminating in the nozzles J and J set at a proper angle with relation to the buckets. When steam is supplied through the nozzles aforesaid, it will impinge on the impact surfaces of the buckets and will thereby cause the rotation of the fan. The steam after striking the buckets will then exhaust into the casing in a direction parallel to the axis of rotation of the fan,

and will be taken up by the current of air created by r the fan.

The reference characters H and G show the direction of the current of air.

In place of steam, compremed air or any other impelling fluid may be used. The claims should be construed accordingly.

What is claimed is: 1. In a tan a casing, a plurality of rotatable vanes within said casing for creating a current or air parallel to the axis of rotation of the said vanes, buckets carried by said vanes at their periphery, and means for causing a jet or steam to impinge upon the buckets aforesaid, whereby the exhaust steam will flow in a direction parallel to the axis of rotation of the vanes and will be taken up by the current of air produced.

2. In a tan, a casing, a plurality of rotatable vanes within said casing for creating a current of air parallel to the axis of rotation of the vanes, buckets carried at the periphery of said vanes the plane of whose impact surfaces is substantially parallel to the axis of rotation of the said vanes, and means for causing a jet of steam to impinge upon the bucketsatoresald, whereby the exhaust steam will new in a direction parallel to the axis of rotation of the vanes and will be taken up by the current or air 1m duced.

In testimony whereof I nflix my signature in presence of two witnesses.
